Big men seem to decline the most. Moreso centers. They can last a decent while, but they have the biggest drop in their effectiveness. Bein slow and big are a dime a dozen. Once the speed goes, the post moves go, and the explosion goes

I guess you have a point in big men. They see more banging and physical play than any other position.

Thats a special situation. even at his old age, he was slowed, but he never relied heavily on speed. He had his fundamental skills down and those never leave you. He also had a goto move that no one could really defend with consistency

It's not about position really, but more on how much a player relies on his athleticism, as opposed to his learning to play without it. Of course the number of good athletic players in a given position will skewer the results towards that position.

I think it's SG. Technically, SG is the position where skill is required the most. Well, skill can only be so affective if the player has the speed and the agility. (unless you're Paul Pierce..i dont get how he's so slow but still gets to drive to the hoop) Once SG's get to a certain age, their speed and agility takes a big hit that goes down like a waterfall.

Probably the swingmen. With centers, you have players like Kareem, Wilt, Moses, Parish, and Shaq who've all had big impacts in later years, with PGs, you have players like Stockton, Kidd, and Nash who've done the same, with PFs you have Malone, Rodman. With swingmen, people have mentioned Jordan and Reggie, but Jordan took almost 5 years off through his career, and Reggie is primarily a shooter. I can't think of any other swingmen that played that great in later years.
